Hi ahdkaw,
as I wrote before the main thing should be, to give children the tools to make good decisions by themselves. And I said that we in Germany are faced much more with nude pictures and so on, and I think it even helped me in my younger days in some way. So I am not into hiding everything from them, which is simply stupid (You pointed that out clearly). But I now know, that it still was good, that I didn't learn everything at once. So people over here learn to deal with sexuality totally different than in the USA. (Maybe one reason, why you find much more American pornographic sites than European.)
So that's in front of everything that comes after.
But I think, that the freedom for children should be limited in some way. For example, I wouldn't let my 3 and 5 year old children watch war or killing on tv. I don't think that they simply would switch over, if they saw someone shot, like You said. Yes, they will learn that men are evil and that they kill each other. But I think there are some other things, they should learn first. E.g. to love somebody, or respect someone you don't love. Yes, after that they will also learn about war, but they might watch it from a different point of view. That's what I think I should be responsable for, not just hiding away everything. Okay, now you should transpose that to the issue of sexuality.
Never stop thinking.
Siegfried.
